Infra-His Block in a Normal Heart
A 55 year old man with history of palpitation was referred for electrophysiologic study. Baseline ECG, physical examination and transthoracic echocardiographic study were normal. Electrophysiologic study revealed normal AH and HV intervals. Pacing of right atrium with a cycle length of 300 msec showed 2:1 AV block. AH interval was 252 msec and the block was infra-his (Figure 1). With continual ...
متن کامل[Permanent His-bundle pacing in patients with infra-Hisian atrioventricular block].
INTRODUCTION AND OBJECTIVES Permanent His-bundle pacing is effective in patients with supra-Hisian atrioventricular block. We report our experience in patients with infra-Hisian atrioventricular block. METHODS The study involved selected patients referred for syncope and intraventricular conduction disturbance, infra-Hisian atrioventricular block, with left ventricular dyssynchrony and no cor...
متن کاملSignificance of block distal to the His bundle induced by atrial pacing in patients with chronic bifascicular block.
Twenty-one of 496 (4%) patients with chronic bifascicular block, studied and followed prospectively, had block distal to the His bundle (BDH) induced by atrial pacing during initial electrophysiologic studies. In six, BDH was noted during pacing-induced atrioventricular (AV) nodal Wenckebach periods (at paced rates of 150--190 beats/min), with BDH in the short HH cycles after the AV nodal block...
متن کاملRapid Atrial Pacing in Man
The first ten cycles following cessation of atrial pacing were evaluated in 44 control subjects (mean age 52.9 ± 14.88 yr) and 39 patients (mean age 62.9 ± 15.41 yr) suspected of having sinus node dysfunction (SND). The maximal cycle length for each postpacing cycle following several pacing periods in each control subject was determined, and was normalized by dividing it by the subject's mean s...
متن کاملRapid reversal of right ventricular pacing–induced cardiomyopathy by His bundle pacing
Case report A 78-year-old woman with hypertension, paroxysmal atrial fibrillation treated with pulmonary vein isolation 4 years prior, and normal biventricular systolic function presented with symptomatic high-grade heart block with junctional escape rhythm and QRS duration of 84 ms (Figure 1A). She underwent dual-chamber pacemaker implantation with apical RV lead placement and resolution of he...
